The UC Santa Barbara sociologist, who is Jewish, sent images from the Holocaust and from Israel's Gaza offensive to students in his class. He has drawn denunciation and support.

Marcuse, who is Jewish and teaches about the Holocaust in his world history and German history classes, said he would not have injected his own views into such a message to students, but added: "I don't think Bill Robinson's e-mail is anti-Semitic in any way. I think criticism of Israel is OK."

One UC Santa Barbara official has already looked into the allegations against Robinson, and a faculty committee is being formed to decide whether to forward the case to UC Santa Barbara Chancellor Henry Yang. A university spokesman declined to comment on the case.

Robinson has hired an attorney, and the student committee supporting him has scheduled a May 14 campus forum on the matter. Joseph and Hausman, the students who filed the original complaints, said they plan to attend. So do Hausman's parents from Los Angeles and Rabbi Aron Hier, director of campus outreach for the Wiesenthal Center.

"I just want to bring awareness," said Hausman, 20. "I want people to know that educators shouldn't be sending out something that is so disturbing."
